.To all whom it may concern.:

Be it known that I, CARLETON Ennis, a citizen of the United States, anda resident of .i New York city, and State of New York, have inventedceri tain new and useful Improvements in Gas- Producer Apparatus, 'ofwhich the following This invention is a division of copending lapplication Serial No. 259,925, relating tol| gas-producer apparatus,and especially to roducts of combustion or a portion thereof iirom Ianyconvenient furnace yielding stack-gases carrying carbon dioXid aredelivered to the producer and passed through the bed of fuel therein. Ihave discovered that these combustion products owing to the presence ofcarbonic acid may be made the means of keepingdown the temperature ofthe producer and of avoiding the production of soot, slag, or clinker inobjectionable amounts. I have also found that 'the use ,of such productsof combustion brings about a more uniform combustion of the fuel withconsequent equality` of temper` ature throughout the fuel mass,`wherebythe. troubles heretofore experienced through the, burning out of theboshes or other metallic parts of the producer are practicallyeliminated. l

Carbon dioxid in passing through a bed of l ignited fuel-of considerabledepth will be reduced to carbon monoxid and in xso doing will i absorbheat, as the splitting off of an atom of oxygen from CO2 by the carbonof the fuel l from carbon monoxid is an endothermic i change. Thisreaction has in addition to the l advantages above mentioned theadvantage e that the reaction of reduction resulting in the endotherlnicabsorption of heat takes place with greater facility than in the case ofsteam and results in the operation of the producer i 'at a much lowertemperature than that possible by the use of steam. `v

This invention comprises novel improvements in apparatus for carryinginto effect thev endothermic` reaction above mentioned and also includescertain useful arrangey ments of conduits, dampers, and jets Where- `inthe county of New York 'said pipe connection by a portion ofthestack-gases maybe divert- 5 I ed from' their usual course into theproducer.

In the accompanying diagrammatic drawing, 1 is a gaseproducer havingfeed-hoppers 2, twyers 3, blast-baille 4, and. water sea 5. The twyers 3are connected with the 5 blower 6. p l

7 is a gasoutlet pipe extending to the furr nace 8, which is shown of areverberatery type, but may be of any form of construction' desired. y ll f From the stack ,9 a passage l() leads to a cap or sleeve 11,situated on the blower 6.' A damper 12 is introduced into this passage.

13 is an air-pipe leading from the air-com presser 14 tothe blower 6. i

15 is au adjustable damper covering the opening of thc sleeve 11.

The method of operation is as follows: A. bedI of fuel of suilicientdepth to produce a com bustiblc gas of good quality and contain- 7 inglittle or no free oxygen is brought to a suitable state of ignition inthe gas-producer 1. The air-compressor 14 is putin operation 'forcing ajet of air into the blower 6, thereby creating a suction in the passage10. Adjustmcnt of the damper 12, and, if necessary, of the damper 15,vis made so that a mixture of air and products of combustion is formed,which when entered into the producer effects a simultaneous exotherniicand endotherlnic reaction, by virtue of which the temperature of theproducer is maintained constant at any desired point.

What I claim is- 1. .In a gas-producing plant, the combina-` tion of agas-producer, a source of products of combustion, a pipe connection fromthe source to the producer and an interposed collar .insaidpipe'connection carrying an air-j et nozzle and having valve-controlledcommuf nication with the atmosphere.

`tion of a gas-producer, a source of products of combustion, a pipeconnection from the source to the producer having a valved inlet open tothe atmosphere and an air-injector in between the inlet and theproducer.
